DENTON COUNTY (CBS 11 NEWS) – An 18-year-old former student and football player at Krum High School is accused of burglary and arson.

William ‘Caz’ Wojciak remained in the Denton County jail Friday evening, on $300,000 bond.

Sheriff’s deputies say Wojciak’s family is trying to get the bond amount lowered, against the recommendation of investigators.

Wojciak last attended Krum High School in 2012-2013. He was a standout quarterback with the Bobcat football team.

“He was a very good athlete from a young age,” said one Krum resident, who says she knows the Wojciak family.

Court records show Wojciak was arrested for credit card abuse in December 2012, and released. Other court documents also show he was arrested for possession of a controlled substance in August 2013.

School officials say Wojciak was dismissed from the football team in August, and is not enrolled in school this year. Six weeks later he is now under investigation for a felony.

On October 2, a home on FM 1173 was destroyed by fire. Upon investigation, the fire marshal found traces of evidence including the smell of gasoline — all indications pointed to arson.

The burned home is the residence of Krum School Board Member Donna Hooper. The Hooper family reported guns and jewelry missing after the fire. They also told investigators the family dog was doused with an accelerant, and set afire. The dog had to be put down due to its injuries.

Two days later, on October 4, the Denton County Sheriff’s Office received a tip that Wojciak was involved in a mass shooting plot at the high school. The claims were investigated, but deputies said the threat was not credible. Wojciak was questioned, but not arrested.

During the threat investigation, sheriff’s deputies learned Wojciak sought medical treatment for burns to his arms.

Through witness statements, and text messages, investigators had probable cause to search Wojciak’s home. “We knew he was inside. He refused to come to the door,” Assistant Chief Deputy Randy Plemons recalled. “Thirty minutes passed by before he did come to the door.”

According to deputies, on October 16, they discovered guns, jewelry and approximately $2,000 in drugs in Wojciak’s bedroom. He was arrested and charged with burglary of habitation with intended other felony (arson).

Many people in Krum, a town of just over 4,000, are shocked by the most recent allegations. “If it’s true it’s really sad. I really feel compassion toward the parents, grandparents. It’s hard to believe,” one resident said.

Wojciak’s parents could not be reached for comment at their home on Friday

The Denton County Sheriff’s Office is also investigating a 17-year-old friend of Wojciak, who was with him at the time of the arrest. The teenager is the ex-boyfriend, deputies say, of a daughter who lived at the Hooper home.

The assistant chief deputy says he expects more charges to come. “We believe it has everything to do with a relationship gone bad. A boyfriend-girlfriend situation. It just happened to be a school board member’s home.”
